Application filed` Erelriruary` 24,` 1920. Serial` No. i #361;025.

To all/whom it may concern:

Be it known that I, THCMASr E. Cnoucii,`

in'night latches, the object being to provideimproved means for securingthe bolt `mechanism to the door independently of the casing so that theoperation'oi' k the bolt may be visibly tested heitere assemblingthe.casing or cover, and it consists ina'spider secured to the door andcarrying thebolt mechanism and a 4casing` i detachably.secured to Vthespider. y l

ltiurther eonsistsin the details of construction as will be more fullyexplained and pointed out in the claims.

In the accompanyingdrawings; Figure 1 is a view `in elevation ofthelatch kand its keeper; 2 a view yin section through the casing,betweenthe wrought metal'plate and the enter, tace ci' the casi-ng towhich the' said plate is attached, and also through the keeper; Fig. 3is a view in elevation of the casing from the open side thereof; Fig. 4is a view in elevation of the spider attached to the door and farryi'ngthefboltz, mechanism; Figx is a view in longitudinal transverse sectionof the latch'and' .its keeper; Fig. 6 -is a view in perslrective'ot thekeeper and Fig. 7 is a view in front elevationfofth casing.

10 represents the spider secured by screws 11 to the door 12 andprovided at one end with the flange 13 slotte'dfor the passage oithebolt 14 whichl'atter is projectedby a spring and is retracted by aroll back 15 on the knob shank 16v, in the usual and well known manner.The bolt may of course be retracted by a mechanism 15al actuated by akey from the outside of the door, in the usual and well known manner.

The spider 10 is also provided at its side 17, each of which is providedwith an outwa1`dlyturned tongue 18 asshown in Figs;

4 andj. i

`The `casing 19 which an integral structure punched and drawn from ametal lank, comprises an outer face plate vand integral' ends and sides,one end Vhaving an opening corresponding in size and [position with theopening in flange 13 of thevr spider for thepassagefoiithe*bolt 14DSecured within the ycasing 19 and against the inner surface oit thelcasing isthe :wrought metal plate 2() havingl lugs ALil" which' enterrecesses in tlie'sides and ends of the casing for perinanently securingit to' the latter. This )late which carries the bolt sto nn" device asshown in Fig. 3,` is provideiilat its opposite sides with the integralright angled hook shaped lugs 21 whichare adapted to engage theoutwardly turned tonguesl on the side flange 17 of the spiderlO'forloeking the casing to the spider and consequently to the door. i

p ln assembling f the parts,-,thel spider or 'frame with the boltassembled therein is secured to the I door and itsl operation visiblytested before applying the 'casing j The lattery is passedoverthefprojecting end ci? the bolt and thenmoved endwise rearwardly untilthe front end of the esingis in contact with'the endr flange 13 ofthespider,

this rearward endwise movement carrying the hook shaped lugs 2l onY thewrought metal plate Q0 under the outwardly turned tongues 18,on thespider. After the parts have vbeen thus assembled and secured,l t-hecasing is further secured tothe spider, by the screws 22 passing throughthe outer end of the'casing and engaging screw threaded holes'23in theend-flange 13 of the spider thus*v positively', locking lthe casing' tothe spider. Togremove the casing the door should be opened so astoexpose the lhead of the screw Q2 and the latter removed. `The casing Visthen moved endwise forwardly so vas to Ydisengage the lugs 21 from thetongues 18 and then by retracting the latch bolt it can be lifted offthe spider.

The bolt may be retracted by the knob at the inner side of the door, andby key mechanim 15a in the usual manner from the outer s1 e.

The knob 24 is provided with a shank 16 which passes through the outerface of the casing and through the wrought metal plate 20 and its end isupset or spun over thev cam or roll back l5 and thus operates topermanently secure the plate 2() to the casing 19.

`The outside sheet 25 of the strike plate or keeper is also drawn from asingle blank A and is provided at the inner face of its front or strikeplate with a steel reinforcing or" provided atits opposite edge withkone or more tongues 31 which rest in recesses or slots in the outsideshell of the strikeV plate or keeper. When the parts of the latter areassembled as shown and secured by rivet 32, the plate 30 is permanentlysecured Within the strike plate so that the latter can be handled as aunit.

It is evident that many slight changes might be resorted to in therelative arrangement of parts shown and described without departing fromthe spirit andscope of my invention. Hence I would have it understoodthat I do not wish to confine myself to the exact constructionandarrangement. of

- parts shown and described but,

. Having fully described my invention what I claim as new and desirey tosecure by Letters-Patent, is

l. The combination of a spider adapted to' be securedto a door, a boltand its mechanism mounted in and carried by the spider,

and a casing detachably secured to the spider. Y

2. The combination of a spider' adapted to be secured to a door, a boltandv its mechanism carried by the spider, a casing, the casing andspider having interlocking engaging means and bolt actuatingv meanscarried by the casing.

3. The combination of a spider adapted to be secured to a door, a boltand itsmechanism carried by the spider, acasing, the casing andy spiderhaving interlocking engaging means whereby the' casing secured inplace.v and removed by an endwise movement,Y and securing means passingthrough one end of the casing and through a member of the spider forlocking the casing against endwise movement.

4. The combination of a spider adapted to be secured to a door andprovidedwith side flanges and an endl flange, a bolt and its mechanismcarried by said spider, a casing havingl securing means interlockingwith lugs on the side flanges of the spider, securing means connectingan end of the casing and the end flange on the spider and bolt actuatingmechanism carried by the casing.

5. The combination of a spider adapted to be securedto a door, a boltand its mechanism carried by the spider, a casing, a plate securedagainst the inner face of the casing and having means for interlockingwith the spider, and means on the casing for actuating the bolt. Y

6. The combination of a spider adapted to be secured to a door, a boltand its mechanism carried by the spider, a easing, a plate securedagainst the inner face of the casing and havingy means for interlockingwith the spider', and a knob on the casing Vfor actuating the bolt, theknob spindle passing through the casing and plate and upset at its innerend against the inner face plate and locking the latter to the easing.y.

7. The combination of a spider adapted to be secured to a door andhaving side flanges, a bolt and its mechanism carried by the spider, acasing, a plate securedA against the inner face of the casing, the saidplate and side anges of the spider having interlocking engaging means,and a knob carried by the casing for actuating the bolt.

8. VThe combinationv of a spider adapted to be secured to a door andhaving side flanges and an end flange, a casing, a plate .secured to thecasing and against the inner surface ofthe outer face of the latter, thesaid plate and spider having interlocking securing means, means passingthrough one end of the casing. and the end flange of the spider forlocking 4the two parts together, a bolt and mechanism carried by thespider and means for actuating the bolt. p

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
